Jay Fields on Unit Testing

I rather enjoyed this interview with Jay. It was nice hearing a reasonable voice in the discussion – namely, there’s no need to be over-zealous about any one approach. Even in my own work I’ve seen a tremendous benefit to testing as I write code. It saves a lot of headache and provides some assurance that things still work down the road when code changes. Of course, as always, you need to be confident your tests are thorough enough in the first place.
